序列化 List<string> 时出错

Question

我正在开发一个 Windows Phone 运行时应用程序，并且我在字符串列表中有数据。但是当我暂停我的应用程序时，出现错误 Error trying to serialize the value to be written to the application data store 和 Additional information: Data of this type is not supported. 它说不支持字符串列表，有人知道我如何解决它吗？

启动时：

protected override void OnLaunched(LaunchActivatedEventArgs e)
{
   if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
       if (ApplicationData.Current.LocalSettings.Values.ContainsKey("lista"))
       {
          lista = (List<string>)    (ApplicationData.Current.LocalSettings.Values["lista"]);
       }       
}

挂起：

private async void App_Suspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
    {
       ApplicationData.Current.LocalSettings.Values["lista"] = App.lista;
    }

App.lista 是在 app.xaml.cs 处声明的列表，如 public static List<string> lista = new List<string>();

Answer 1

您必须自己 serialize/deserialize 该列表，例如：

string Serialize(List<string> list)
{
    StringBuilder result = new StringBuilder();

    foreach (string s in list)
    {
        result.AppendFormat("{0}{1}", result.Length > 0 ? "," : "", s);
    }

    return result.ToString();
}

List<string> Deserialize(string s)
{
    return new List<string>(s.Split(','));
}

如果您的字符串可能包含逗号，请相应地进行编码。
